- b)Mass only exists on Earth
- c)Mass and weight are the same
- d)Mass measures inertia, while weight measures gravitational force
Correct answer is option 'D'. Can you explain this answer?
Most Upvoted Answer
What is the relationship between mass and weight?a) Weight is constant...
Mass measures the amount of matter in an object and is constant regardless of location, while weight measures the gravitational force acting on that mass. Weight can change depending on the strength of the gravitational field, such as on different planets.

What is the relationship between mass and weight?a) Weight is constant...
Understanding Mass and Weight
Mass and weight are fundamental concepts in physics, often confused but distinctly different in nature.
Definition of Mass
- Mass is a measure of the amount of matter in an object.
- It is a scalar quantity, meaning it has magnitude but no direction.
- Mass is constant regardless of location; it remains the same whether you are on Earth, the Moon, or in space.
Definition of Weight
- Weight is the force exerted by gravity on an object.
- It is a vector quantity, meaning it has both magnitude and direction (towards the center of the Earth).
- Weight can change depending on the gravitational field strength. For example, an object weighs less on the Moon than on Earth due to weaker gravity.
Relationship Between Mass and Weight
- The relationship is expressed by the equation: Weight = Mass × Gravitational Acceleration (W = m × g).
- While mass is a measure of how much matter is in an object, weight measures the gravitational force acting on that mass.
Inertia and Gravitational Force
- Mass measures inertia, which is an object's resistance to changes in its state of motion. A larger mass means greater inertia.
- Weight measures how strongly gravity pulls down on that mass. This is why weight varies with gravity, while mass does not.
In summary, mass and weight are related but represent different physical properties. Understanding this distinction is crucial for grasping basic principles of physics.
